The chart was launched as
The Big Top 40 Show on 14 June 2009. Between 2010 and 2018, the programme was sponsored by
Vodafone, becoming
The Vodafone Freebees Big Top 40 (later
The Vodafone Big Top 40 and
The Official Vodafone Big Top 40). For the first time, listeners could change the chart during the show by downloading tracks on
iTunes. Songs 40 to 11 are played before the new Top 10 is finalised at 6:10pm, with iTunes sales during the show taken into account. The show, originally produced by Paul Armstrong and Paddy Bunce, was the first real-time chart show broadcast on UK radio. In September 2018,
Bauer announced that their
Hits Radio Network would stop carrying the show after the expiration of its contract at the end of 2018. Global, which produced the show, made the decision to withdraw the programme from syndication to the wider commercial radio network. The final show across the commercial radio network aired on 30 December 2018. The relaunched show,
The Official Big Top 40, started in January 2019 and is widely available on
Capital and
Heart. After an appeal from the
Official Charts Company to the
Advertising Standards Authority, Global was ordered not to refer to the show as "The Official Big Top 40", and subsequently updated the name to "The Official Big Top 40 from Global".] In September 2024, the show gained a new sponsorship and was renamed to "The
EE Official Big Top 40 from Global". ==Presenters and producers==
